Cable inspection labels with the imprint: "Nächster Prüftermin: Geprüft gemäß VDE Elektro-Prüfung" is attached to the inspection report and the inspected cable after passing the VDE testing. In this manner, the electrical inspection labell gives the user of the device the information, when the cable was last tested and when it needs to be tested again. The clear and self adhesive foil is a protective laminate, which seals its inscription on the label. With smaller cable diameters, the cable inspection labels can be used as cable flags.

The VDE Electrical inspection is an important aspect of yearly maintenance and inspection of company-owned electrical devices and machines. According to the regulation, all electrical machines and devices must be tested according to a determined test procedure consisting of a visual inspection and various readings by an electrically qualified person or under the direction and supervision of such.
